Why it’s this loud
3.9
Volumes of CO₂ in every can. Most sodas sit between 2.5 and 3.5.
01
Filled at 1 °C
Cold liquid holds more fizz, so every can is filled just above freezing. Warmer fills go flat faster, and you can taste it.
02
Pushed to 3.9 volumes
That’s more carbonation than most sodas and about the same as a good sparkling water. The first sip bites back.
03
Real juice, not syrup
Juice and zest oils go in before the gas, so the fruit rides up on the bubbles instead of sitting at the bottom.
04
The crack, measured
We recorded it in a quiet room: about 78 dB at arm’s length. Loud enough to turn heads in an open-plan office.

I film at six in the morning before the park fills up. Siren is the can that's always in my bag.

Sour apple, chalked hands, one more try. That's the whole afternoon.

Build it at dawn, ride it at dusk. Floodlight in between.

Cold can after the last rep. That's the whole ritual.

Blackout

First light, second can. The ocean doesn't care what time it is.

Siren
Siren Spritz
Blood orange over lots of ice with a splash of soda and a rosemary sprig. The easiest good drink there is.

4 min
Static
Static Smash
Muddled mint, lime and cucumber with sour apple poured over the top. Sharp, green and very cold.

3 min
Floodlight
Floodlight Lemonade
Half Floodlight, half fresh lemonade, with a thin lemon wheel. Tastes like the first warm day of the year.
